FLT3L and granulocyte macrophage colony-stimulating factor enhance the anti-tumor and immune effects of an HPV16 E6/E7 vaccine


Figure 5. The nucleic acid vaccine inhibited tumor metastasis in vivo. Mice (6–8 weeks old) were randomly divided into five groups (five mice/group). The mice were immunized, and their tumor sizes and metastasis sites were detected with an IVIS after two weeks (A), four weeks (B) and six weeks (C). (D) The survival rates of mice in the blank, pVAX1-IRES (NC), pVAX1-IRES-FLT3L (FLT3L), pVAX1-IRES-GM-CSF-B7.1-HPV16 E6/E7 (HPV16) and pVAX1-IRES-GM-CSF-B7.1-HPV16 E6/E7-FLT3L (HPV16+FLT3L) groups were calculated at different time points.
